• example fluorescence region:
  • learned that it's not possible to correlate against the position of the grid label
  • correlation needs to be relative to landmarks within the sample itself, which would require an irregular distribution of beads

• EM of sections from that region:

  

  

  

  

  • maybe this is an actin tail? too bad we can't correlate to fluorescence

finished writing up all equations for membrane-only mechanics model

The dynamics of the \(i\)'th segment are governed by

\begin{subequations} \begin{align} \dot r_i=-\frac{\Gamma}{\Delta A_i}\frac{dF}{dr_i}\\ \dot z_i=-\frac{\Gamma}{\Delta A_i}\frac{dF}{dz_i} \end{align} \end{subequations}

where

\begin{equation} F=F_H + F_\gamma +F_V\ \end{equation} \begin{equation} F_H=&2\kappa_3 \left( \left(H(r_1, z_1) - H_3 \right) \Delta A_1 + \sum_{i=2}^{3N-1} \left(H(r_i, z_i) - H_3 \right) \Delta A_i + \left(H(r_{3N}, z_{3N}) - H_3 \right) \Delta A_{3N} \right) \end{equation} \begin{equation} F_\gamma=&(\sigma-\gamma_3)\left(\Delta A_1 + \sum_{i=2}^{3N-1} \Delta A_{i} + \Delta A_{3N} - \pi r_{3N}^2\right) \end{equation} \begin{equation} F_V=&P\left(\Delta V_{1} + \sum_{i=2}^{3N-1} \Delta V_{i} + \Delta V_{3 N}\right) \end{equation}

starting to write up code for simulating the model
